Domestic hot water plate heat exchanger is to meet the urban and rural workers and factories and mines with heat and ensure that the shower, washing with the necessary equipment, which is characterized by a large number of wide, requiring a safe supply, continuous, easy to use.

Domestic hot water is generally used between 25 ~ 60 ?, is a low-temperature thermal energy use, low-grade heat carrier mass. For domestic hot water heat exchange supply is very suitable to achieve energy saving, safety, reliability and efficiency requirements.

To ensure the safety and stability of the plate heat exchanger for domestic hot water supply, the following points should be noted.

1. belong to the low-temperature heat source heat exchange system (water temperature is not greater than 70 ?), normal water quality 1 will not occur scaling phenomenon, even if the deposition of a thin layer of scale, with tap water flushing can be removed. Therefore, this type of heat exchange device management and maintenance less, without frequent maintenance, the effect is better.

2. When preparing domestic hot water with high temperature heat source, the general hot water system water temperature is greater than 70 ?, if the water quality is hard, the system equipment is easy to scale, will affect the use of effect and life.
3. In order to give full play to the advantages and characteristics of the plate heat exchanger, the heat source and water quality should be very applicable situation, differentiated treatment, to take a variety of measures, such as domestic hot water supply system in the water temperature should not exceed 70 ?; water quality is not good to add water treatment; try to use low-grade heat sources, in order to play the plate heat exchanger's special features. This will achieve greater economic and social benefits.
